- To all whom it may concern:

,Be it known that I, HEN Y Man'rrnson,

" a'citizen of-the United States, residing at Elbow Lake, in the countyof "Grant "and State of Minnesota, have invented a new and usefulSeparator, of whichthe following is a' specification.

This invention relates to separators espe cially designedfor usein theseparation of wild oats, wheat, etc), one of its objects beingto'pro'vide, in connection with: the separating screens, a meansjwherebythe-wild oats are retarded and held in their downward movement fromthescreens, thus to separate over the said means. I 1 I Afurtherobjectis to tlifein i'rom the wheat which passesfreely provide retarding meanswhich canbe'adjustedtosuit the kind ofgrainwithwhich it is used.

Another objectisto'provide a means forv keeping the 'grain'spread out,while de f scending. Q 7 1 j i I With the foregoing @an'df; ther'jobjects in viewwhich will appear as; the 1 description proceeds,theinvention resides in the comblnatlon and arrangement of-parts and. 1n

- the details of construction hereinafter clescribed and claimed, itbeing understood that changes in the precise embodiment of the inventionherein disclosed, can be made within the scope of what is clalmed,without departing from'the spirit of the invention. 1

In the accompanying drawings, the preferred form of the invention hasbeen shown. In said drawings :-Figure 1 is a vertical section throughthe machine on the line AB Fig. 2. Fig. 2 is a plan view; Fig. 3 is asection on the line 6-1) Fig. 1. Fig. 4:

is an enlarged section through a portion of.

the apron. v I

I Referring to the'figures bycharacters of reference 1 designatesstandards supporting a hopper 2 provided with a gate valve 3. for

. controlling the outflow of grain onto a board C 4 located at 'theupperend of ascreen This screen is suspended in an -lIlCl1Il6d'POS1- tionbelow the ,hopper by llIlkS'fi. and has a .hopper 7 arranged thereunderandmovable therewith, this hopper extending; the full length of thescreen. Said hopper 7 has an outlet 8 through which screenings pass ontoan inclined plate .9supported by inclined side strips 10 securedtostandards 1. This inclined plate has a diagonally disposed de-:

flecting flange ll at its lower edge for diverting screeningslaterallyintoa spout12.

roller supported by" the upper ends of-str1ps'l0 anda board 14 isalsosupported and extends throughout the greater portion ofthe lengththereof, Another roller 15 is journaled in arms-16f 10'- ;cated betweenthe lower ends oflstripsl0 andthese'arms have slots 17 for the receptionof bolts 18 engaging strips 10. Thus it will be seen that arms 16 can beadjusted angularly and longitudinally to bring the roller 15 to anydesired position relative to the lower end of board" 14.. An lendlessapron 19, preferably formedof flannel .hav-

ing acanvas backing, ismounted on the rollers and hasitsupperfiight'supported by and slidable 'on the board 1 1 and extending under theplate 9.; 7

Cross strips 20 are secured to the side strips 10 and are located closetobut'spaced from the apron.

EXtendingfromthe delivery end of screen 5 at the sides thereof are arms21 to which is secureda coarse, mesh screen 22 onto which the tailingsfrom screen 5 are adapted to discharge. This screenextends up totheroller 13 and is designed to project thereover during thereciprocationof the screen so that tailings from screen "5 will bedischarged over the roller 13. Secured toand revoluble with roller 13 isa wheel 23 which oan be in the formof a pulley or'a sprocket-and whichtransmits motion through a beltor chain 24 to a wheel 25 secured to ashaft 26. This shaft is journaled on certain of the standards 1 andhas-cranks 26 mounted in slots 28 formed in links 29 which are pivotallyconnected to the sides of the hopper 7.

It is to be understood that when the wheel 23 is set in motion in the,direction indicated by arrows, the belt will be actuated, the upperflight thereof moving upwardly over theboard 14. Motion will betransmitted through wheel 23, belt or chain 24: and wheel 25 to shaft26and the links 29 will thus rapidly reciprocate the screens.

By opening the valve 3 grain contained in hopper 2 will gravitate ontoboard& and thence to screen 5 along which it will be -worked by thereciprocation of the screen.

The fine particles will fall through the screen and onto the plate. 9from which they willbe discharged through s out 12. The remainder of thegrain will ow off of the end of screen 5 and onto the coarse screen 22where a separation will again be elitected, the grain falling throughscreen 22 while large undesirable particles, such as stones, will bedischarged as tailings over the'up per end of apronm19. The grainfalling through screen 22 will drop onto j upwardly moving upper flightof apron 19 and its downward movement-due to gravitation will" be partlyoffset by the upwardmovement of the portion of the upper the apronflight so that the descent of the grain will be very slow.v Consequentlyany Wild oats mixed with the wheat or-other grain, will have ample timeto'become en- 1 tangled in the "woolly nap or finish of the.fiannelffwhile the wheat will slowly "slide; downwardly over the apron.The strips20,

keep the grain spread out over the apron so that the grain will notpile, up and jump off ofthe'apron. The entangled wild oats will becarried up by the apron and canbe removed therefrom in any suitablemanner,

as by -means of a scraping wire 30,.

Byraising and lowering the roller 15 and thelower' portion of the apronthe afppara tus can beada'pted for use with different kinds of grain.For example, where wheat, is tobe' separated, the degree of rise of rtheapron should be less thanlwhere cats are beingseparated.
